MACHINE FOR MAKING HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 386,904-, dated July31, 1888.

Application filed December 31, 1887. Serial No. 259,475. (No model.)

To all whom, it may concern,.-

Be it known that I, AUGUST M. SWEDER, a citizen of the United States,residing at Marquette, county of Marquette, State of Michigan,haveinventedacertain new and useful Improvement in Machines forManufacturing Horseshoes; and I declare the following to be a full,clear, and exact description of the invention, such. as will enableothers skilled in 1o the art to which it appertains to makeand use thesame, reference being had to the accompanying drawings, which form apart of this specication.

My invention pertains to a novel machine r 5 for the manufacture ofhorseshoes; and it consists of the construction, arrangement, andcombinations of devices and appliances hereinafter specitied,and moreparticularly pointed out in the claims.

The purpose of the machine embodying my invention is to provide anexpeditious device whereby the manufacture of horseshoes may be easilyand economically accomplished and their production not only increased inquanz5 tity, but also in their uniform quality, so as to be of superiorefficiency. This purpose I secure, essentially, first, by providing themachine with devices for cutting from a bar of iron a bar of sufficientlength as may be desired for forming the body of the shoe with itsheel-calks; second, by providing the machine with presses of suitableform to shape the body of the shoe about an intermediate die orpatternblock; third, by providing 3 5 mechanism to carry the clipped barfrom the knife to said presses; fourth, by providing mechanism tooperate said presses to secure the bending of the bar into the form ofthe shoe; iifth, by providing an auxiliary press to 4o turn thehcel-calks; sixth, by providing the machine with an additional press andstamp lo perforate the shoe for the reception of the nails, and toprevent the lateral spread of the metal in shaping the body ofthe shoe;seventh, by providing means for releasing the shoe from the machine whenthe process of its manufacture is completed; and,eighth,my inventionembraces all other general and specifre construction and operation ofparts illus- 5o trated in the accompanying drawings, which forma part ofthis specification, andas herein set forth.

In the drawings, Figure l is a side elevation ofa device embodying myinvention. Fig.

2 is a vertical cross-section along the linem y 55 of Fig. 1. Fig. 3 isafront elevation showing portions of the invention. Fig. 4 is a separateview of the arm F, showing the bridge G in section. Fig. 5 is a separateview of the die in its pedestal in side elevation. Fig. 6 6o is a frontview of the same with the shapingpresses in position thereon. Fig. 7 isa side elevation of a portion of the reciprocatory press; Fig. 8, afrontView of the same. Fig.

9 is a front view of the stamp; Fig. 10, a side 65 View thereof; Fig.11, a separate view of the bridges A and G,with adjustable mechanism.Fig. l2 is a separate view of the auxiliary press L.

I carry out my invention as follows: 7o

In the drawings, A represents any supporting bed and frame.

B is the driving-gear, mounted upon the driving-shaft B and meshing withthe gear O, mounted upon the driving-arbor C', provided 75 with a seriesof eccentrics, as hereinafter explained, and also with a gear for`driving one of the presses, as further explained in its order. Theeccentric c, located upon said arbor, is arranged to operate upon areciprocatory bar, D, to depress said bar, the bar having a pivotalengagement, d, with a cutter-arm, D', which may be pivotally engaged atits opposite end upon a bridge, A@ as shown at a. rPhe cutter-arm isprovided with a cutter-blade, D2, and any suitable retracting-spring,D3. Said arm is made open or bifurcated at its outer end to permit thepassage of the metal bar E, supported upon the bridge A. lt is evident,thus, that when the reciprocatory bar D is depressed 9o by the eccentricc the metal bar will be severed by the cutter-blade upon the arm D',which arm will then be retracted into its normal position.

The severed end E', of suitable length to con- 95 stitute the body ofthe shoe with its heel-calks, is carried to the shaping-presses by meansof a vibratory arm, F, having its upper end movable in a bridge, G, theconstruction and arrangement being such that as the head of the roovibratory arm is thrown in the direction of said presses the severed endof the metal bar will be carried thereto.

The vibratory arm may be pivot-all y engaged,

as at f, upon the supporting-frame, its lower end projected beyond saidpivotal engage ment, as shown in Fig. 1, to constitute a lever for thevibration of the arm. Thislever end of said arm has a jointedengagement, as at f', with a connecting-rod, F', united at its upper endwith the arm H, operated by the eccentric c. As thus constructed, itwill be seen that when the eccentric c' operates the arm H and itsconnecting-rod F' the vibratoryV arm will be thrown to carry the iron`to the presses. Said arm may then be retracted by any suitable spring,F.

I l' are the shaping-presses, having their faces curved into suitableform to shape the bar E' to constitute the body ofthe shoe, and flanged,as shown at i i', toreceive and retain said bar. Said presses arepivotally engaged at one end upon a supporting-pedestal, A2, and have asimilar engagement at their opposite ends, as shown at i2 i, withsuitable connecting-rods, respectively, .I J', which rods are operatedby eccentrics c2 c3, respectively, on the arbor C. Thus the presses maybe opened and closed, as shown in the two said4 positions in Fig. 1infull and in dotted lines, their position being actuated by theeccentrics c" c3.

Secured upon the pedestal A2 is a center die or pattern-head, K, itsperiphery being of the desired form of the shoe. This die or head may bemade relnovable and engaged upon the pedestal in any desired manner toform a center bearing, about Which the metal is shaped into the properoutline of the shoe as the presses are operated.

Toform the heel-calks,IproVide an auxiliary press, L, pivotally engagedupon the said pedestal A2, as shown atl. This press is engaged,pivotally intermediate of its extremities, as shown in Fig. 2, so as tohavea suitable motion. At one end said press is engaged also withaneccentric, c4, upon the arbor C' by a connectingrod, M, having ajointed union with the press, as shown at m. The opposite end of thepress is preferably forked, as shown in Fig. 12, and its forkedextremities arranged to bear upon the extremities of the shoe and bendthe metal to form the calks at the heel.

N represents a reciprocatory press eccentrically engaged at one end upona shaft, O, by means of a sliding head, N', operating upon asupporting-bed, P. The eccentric engagement of said head upon said shaftis shown in Fig. 2 at u. This shaft is driven by a gear, O', meshingwith a gear, O", upon the arbor C'.

Q is a stamp engaged upon the end of the press N, and held in place' inany proper manner, as by a set-screw, n'. The stamp is flanged upon itsface to embrace the outer edges of the metal and prevent the yielding ofthe met-al. The stamp may also be recessed,

as at q, Fig. 10, for the operation ofthe shap ing-presses.

Within the recess q of the stamp are located a series of small punches,g3, for the purpose of perforating the shoe to receive the nails, andwhich is accomplished by the reciprocation of the press N. These punchesmay be removable. The pedestal A2 may be suitably perforated, as at a',to permit the ready discharge of the chips punched from the shoe.

To release the shoe any desired device may beused-as, for instance, anarm, R, may be engaged upon the bed P to throw off the shoe as the pressN is retracted. The shoe naturally adheres to the stamp Q as the pressis drawn backward. I prefer, however, a construction shown in Figs. 7and 8, where the press N is shown provided with thebars Rengaged in theorifices g* of the stamp and provided with retracting-springs r. Theinner ends of said bars are made to abut against a stationary yoke, N,engaged upon the pedestal or bed P, as shown at n2. It will be seen thatas soon as the press moves rearward the heads of the bolts will crowdthe shoe oft.

It will be seen that the bed P and pedestal A2 are but parts of thegeneral bed or frame A.

By making the pattern-head K and stamp Q removable others of desiredsize may readily ta'ke their places for the manufacture ofdifferent-sized shoes. For this purpose it is also desirable to make thepresses I I' removable. Accordingly, said presses and the head K may beremovably engaged upon the pedestal' Az directly; but I prefer to engagesaid devices upon a removable face-plate, K', engaged upon saidpedestal. Moreover, in the manufacture of various sizes of shoes, itwill be necessary to control the length of metal to be cut from the barE. This may be done as follows: The bridge G, as shown in Fig. 11, maybe provided with an adjustable stop, g, operated by a suitable lever,G', pivotally engaged or fulcrumed upon said bridge, as at g',

said lever at its outer end movable along an arc, a2, upon the frame,said arc provided with an elongated slot, in which the lever may be setVat any desired point by a set-screw, g".

By a proper mechanical arrangement and adjustment of parts the differentsteps in the process of manufacture of the shoes may be made to takeplace consecutively in desired relation and order with accuracy andprecision. The various features are simple in con-v roo struction andoperation, not likely to get out y of order, and thereby a considerablenumber of shoes may be turned out per minute and perfect in theirconstruction.
